ob-gyne Flashcards
endometrial histologic features:
proliferative? early secretory? late secretory?
🔹proliferative: straight to slightly coiled glands; tubular glands - pseudostratified columnar; scattered mitoses
🔹 early: coiled; simple columnar; clear subnuclear vacuoles
🔹 late: serrated, dilated glands; short columnar cells
first sign of ovulation
subnuclear vacuoles and pseudostratification
days 21 to 24
“window of implantation”
primary cause of endometrial ischemia and tissue degeneration
resultant stasis
potent inducer of angiogenesis and vascular permeability factors; vasoconstriction of spiral arteries
PGF 2-alpha
enkephalinase activity is highest at what phase of menstruation
midluteal phase
greatest transverse diameter of the head
bitemporal diameter
8.0cm
plane that corresponds to the greatest circumference of the head
occipitofrontal
34.5 cms
plane that corresponds to the smallest circumference of the head
suboccipitobregmatic
32 cms
principal prostaglandin of endothelium
prostacyclin
cervical mucus during pregnancy is rich in?
🔹 Ig
🔹 cytokines
endocervical gland hyperplasia and hypersecretory appearance of the cervix
arias-stella reaction
average weight gain during pregnancy
12.5 kgs or 27.5 lbs
estimated additional energy demands during pregnancy
1st tri: 85 kcal/day
2nd tri: 285 kcal/day
3rd tri: 475 kcal/day
cervical stretching during dilatation; stripping of fetal membranes increase blood levels of prostaglandin F 2a metabolite
ferguson reflex
most effective methods of intrapartum pain relief
neuraxial analgesia
single most consistent determinant of maleness
Y chromosome
pathognomonic is a translucent vertical line at the midline
adhesive vulvitis
🔹 precocious puberty
🔹 pigmentation
🔹 polyostotic fibrous dysplasia
McCune Albright syndrome
- a rare somatic mutation in neural crest cells
isolated gonadotropin deficiency associated with anosmia
kallman’s syndrome
triad of:
🔹 obesity
🔹 hirsutism
🔹 amenorrhea
PCOS aka stein-leventhial syndrome
pituitary cell destruction as a result of hypotensive episode during pregnancy
sheehan’s syndrome
exposure to DES in-utero
🔹 cervical hypoplasia 🔹 cervical collars 🔹 cervical hoods 🔹 cock's comb appearance 🔹 pseudopolyps
cardinal features of endometriosis
🔹 ectopic endometrial glands
🔹 ectopic endometrial aroma
🔹 hemorrhage on adjacent tissues
most important determinant for pre malignant potential in endometrial hyperplasia
cytologic atypia through endometrial sampling
virchow’s triad in abruptio placenta
🔹 vaginal bleeding after 20 weeks
🔹 ⬆️ uterine tone
🔹 abdominal pain, uterine tenderness or back pain
happy happy birthday anne!!! 26 ka naaaaa.. stay young at heart..hehe
love you! 😊
blood infiltrates the myometrium beneath the uterine serosa, seldom interferes with myometrial contractions
couvelaire uterus
most abundant secretory product of the placenta
human chorionic somatomammotropin produced only by syncitiotrophoblasts; it has a strong lypolytic and anti-insulin action
MEIGs syndrome
🔹ovarian fibroma
🔹ascites
🔹hydrothorax
thromboxane vs prostacyclin
thromboxane: platelet-derived vasoconstrictor
prostacyclin: endothelium-derived vasodilatior
